FIELD: machine building.
SUBSTANCE: sealing device has a bearing assembly and a nozzle with a circular longitudinal groove designed on the edge, located on the neck of the roller, a lid covering the bearing with a socket for installation of a sealing sleeve, which includes a housing, a radial sponge with a working edge, interacting with the radial surface of the nozzle. Reliable contact of the working edges with the surfaces of the nozzle when changing position of the rubbing surfaces of the roller relative to sponge cuff is ensured by the fact that the cuff is provided with a second radial sponge, which is connected with the end of the body on the outer diameter, and interacting with its working edge of the outer radial surface of a slot of the nozzle.
EFFECT: reliability improvement of seal of the bearing rolls.
